Coal &Natural Gas.

1. Coal &Natural Gas. Adriana Martinez

2. Coal is used for electricity generation, steel production, and cement manufacturing. • The effect of Coal on Earth are that when large enough amounts of Coal are burned, sulfur combines with oxygen , forming sulfur dioxide; which can be a major source of air pollution. • The effect s of Coal on organisms are that since the burning of coal is a cause of air pollution, animals that inhale the pollution filled air are harmed health-wise.

3. Coal is converted into useful energy is along process. It starts with a machine pulverizes the coal into a fine powder. The coal powder, then mixes with hot air so that it burns more efficiently, then it is transferred to a water boiler, where it creates steam. The steam rises to a turbine, which is spun mechanically, the spinning turbine is used to power a generator, which turns mechanical energy into electric energy. • There are no potential dangers using or transporting this resource. • The use of Coal for energy are very harmful to the environment, as they cause air pollution.

4. Natural Gas is used to generate electricity. • Natural Gas is the cleanest of all fossil fuels, however, it does cause air pollution; which can be harmful to the environment as it causes acid rain . • Natural Gas affects organisms by creating air pollution, which causes acid rain that can contaminate water and harm plants .

5. Dangers transporting Natural Gas consist of explosions . • In November 1974, thirty-three crew members died in a huge explosion and fire that occurred when a tanker carrying liquefied petroleum gas and naphtha collided with a cargo ship in Tokyo Bay. The tanker was towed outside the bay and sunk with torpedoes fired from a submarine and destroyer and still continued to burn for more 20 days.
